Application filed July 2, 1920. Serial No. 393,628.

To all whomit may concern:

Be it known that I, JAMES W. MoFAn- LAND, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Radiator Constructions, of which the following is a specification.

This invention relates to radiator constructions of the typecomprising a plurality of water cells arranged alongside one another in spaced relation.

It is the object of the invention to provide improved spacers between the water cells which are adapted to increase the circulation of air between the water cells.

The invention will be readily understood from the following description of the accompanying drawings, in which Figure 1 is a front elevation of aradiator constructed in accordance with the invention.

Fig. 2 is a fragmentary detail view of adjacent water cells of the radiator with the improved spacer interposed between the same. i

Fig. 3 is a transverse section on the line 33 of Fig. 2. v

Fig. t is a detail longitudinal section on the line H of Fig. 3.

Fig. 5 is a side elevation of the improved spacer.

In the present embodiment of-the invention a usual radiator casing is shown at 1 having a radiator core mounted therein consisting of a plurality of vertical water cells arranged alongside one another in spaced relation. These cells may be of any well known or preferred construction and for the purpose of illustration I have shown the cells as each comprising spaced walls 2 each having laterally off-set reverse bends 4 extending from opposite sides of the water cells in staggered relation lengthwise thereof. A water channel 5 is formed between the spaced walls comprising the water cell. The water cells are, preferably, arranged in parallel spaced relation with the off-sets t of adjacent cells which extend toward one another arranged in staggered relation lengthwise of the cells.

The improved spacer provided between adjacent water cells, preferably, consists of plates 6 lying against one another and each formed with laterally offset reverse bends 7 projecting from opposite sides of the plates tending projections 8, each row of which,

preferably, includes a plurality of said projections arranged one beyond the other transversely of the spacer plates as clearly shown in Fig. 3. The ends of each of these projections are slotted as shown at 9 and the end tips of the projections, are outwardly bent as shown at 10 to provide bafl'les arranged to guide the air passing along the spacer plates into the slots 9 for causing circulation of said air in the spaces 11 provided between the opposite disposed projections 8 of the spacer plates lying against one an- 'other.

By the construction as thus set forth it will be seen that means are provided for positively spacing the water cells of a radiator, said spacing means being so arranged as to induce circulation of air through the spaces between the plates forming said spacer means.

Various changes may be made without departing from the spirit of the invention as claimed.

What is claimed is:

1. A radiator construction comprising spaced water cells, and spacer plates between said cclls arranged face to face and having alined offsets forming cooperating grooves in the contacting surfaces of said plates, the ends of said offsets being slotted with the ends thereof outwardly bent to form battles for guiding air through said slots'and-into the spaces formed between said spacer plates by said cooperating grooves.

2. A radiator construction comprising spaced water cells, and spacer plates between said cells arranged face to face and having alternate outwardly extending reverse bends projecting to said water cells, said spacer plates also having alined offsets forming cooperating grooves in the contacting surfaces of said plates, the ends of said oflsets being open to permit the passage of air into the 7 spaces formed betweensaid'spacer plates by said cooperating grooves.

3. A radiator construction comprising spaced water cells. each having outwardly extending reverse bends, and spacer plates between said cells arranged face to face and having alternate outwardly extendlng re 10 Verse bends projecting to said water cells
